Fractals are very complex pictures generated by a computer from a single formula. They are created using iterations. This means one formula is repeated with slightly different values over and over again, taking into account the results from the previous iteration What are Fractals? n Mathematical expressions n Approach infinity in organized way n Utilizes recursion on computers n Popularized by Benoit Mandelbrot (Yale university) n Dimensional: n Line is one-dimensional n Plane is two-dimensional n Defined in terms of self-similarit

Property of self-similarity means that the parts are similar to the whole, with variations. Fig.2 contains, on the left side, a zoomed-out image of Sierpinski Gasket, the poster child of fractals, and on the right side, there is a zoomed-in image, revealing the scaling and self-similarity the characterize fractals.[17 Fractals can also be classified according to their self-similarity. There are three types of self-similarity found in fractals: Exact self-similarity — This is the strongest type of self-similarity; the fractal appears identical at different scales. Fractals defined by iterated function systems often display exact self-similarity A Fractal World [29] aims at generating fully-mathematical planets using a configurable amount of detail and computing power and to serve as a powerful educational tool for computer graphics. There has been considerable interest recently in chaos theory and fractal geometry as we find that many processes in the world can be accurately described using that theory. The computer graphics industry is rapidly incorporating these techniques to generate stunningly beautiful images as well as realistic natural looking structures Fractals contain their scale down, rotate and skew replicas embedded in them. Many different types of fractals have come into limelight since their origin

the fractal square. If one is interested in defining a square fractal containing the next higher generation it is only necessary to increase n to n+1 in the L=1/3 n lengths of the basic five element code and superimpose the result unto the exposed line edges of the nth generation squares Approximate fractals are easily found in nature. These objects display self-similar structure over an extended, but finite, scale range. Examples include clouds, snow flakes, mountains, river networks, cauliflower or broccoli, and systems of blood vessels.. Trees and ferns are fractal in nature and can be modeled on a computer by using a recursive algorithm In 1975, Benoit Mandelbrot coined the term fractal when studying self- similarity. He also de ned fractal dimension and provided fractal examples made with computer. Mandelbrot also de ned a very well known fractal called Mandelbrot Set

Lastly, our computer graphics favourite fBM, H=1 (G=0.5), generates a spectral density plot with a 9 db/Octave decay, which means the energy is inversely proportional to the cube of the frequency (f-3, B=3). This is an even lower frequency signal, which corresponds with a process with positively correlated memory as we mentioned in the intro A deterministic self-similar fractal is geometrically constructed by starting with the given geometric shape termed as initiator. The initiator subparts are replaced with the pattern, termed as generator. For instance, the initiator and generator from the above figure is used for constructing good patterns Newton's method for cubics, an algorithm more in­ volved than the self-squaring process so familiar to STAGGERED ALTERNATION fractal devotees.

Applications of Fractals : The basic idea of Fractals is to find regularities in the existing irregularities. Below given are some applications of Fractals : Fractal image compression is used in computer science, based on the facts of fractal geometry. By using this technique image is much more compressed as compared to JPEG, GIF, etc Based on this, multi-fractal spectrum features of photo response non-uniformity noise (PRNU) are used for the identification of natural images and computer generated graphics. 9 dimensions of texture features including the square of the maximum difference in fractal dimension (SMDF), the square of the maximum difference in the singularity. If you are wondering how to theoretically make one, it involves iteration. One of the answers discusses the reiteration of removing and adding on equivalent size line segments to create the Koch curve or snowflake. The other is the reiteration of. The Julia set is associated with those points z = x + iy on the complex plane for which the series zn+1 = zn2 + c does not tend to infinity. c is a complex constant, one gets a different Julia set for each c. The initial value z0 for the series is each point in the image plane. The well known Mandelbrot set forms a kind of index into the Julia set The sorts of fractals that are used in computer graphics tend not to be mathematically interesting. When people use fractals to generate, say, a tree or a mountain, they're not really replicating the behavior of a tree or mountain in a nontrivial way; they're just making something that looks more like a tree or mountain to a person than the last generation of art did

The history of fractals traces a path from chiefly theoretical studies to modern applications in computer graphics, with several notable people contributing canonical fractal forms along the way. [9] [10] A common theme in ancient traditional African architecture is the use of fractal scaling, whereby small parts of the structure tend to look. Fractals are a part of fractal geometry, which is a branch of mathematics concerned with irregular patterns made of parts that are in some way similar to the whole (e.g.: twigs and tree branches). Fractal geometry should not be confused with conventional geometry

Introduction: A wire frame model is a visual presentation of a three dimensional or physical object used in 3D computer graphics. It is created by specifying each edge of the physical object where two mathematically continuous smooth surfaces meet, or by connecting an object's constituent vertices using straight lines or curves 9.

TIP: Many computer graphics are created using fractals. Most shapes we see in nature can be created with a simple function by defining roughness. For example, a computer can generate a mountain range if given a fractal dimension between 2 and 3. [8] FACT: A lot of today's technology wouldn't be possible without fractal geometry. Most. The beauty of fractals has made them a key element in computer graphics. Fractals have also been used to compress still and video images on computers. In 1987, English-born mathematician Dr. Michael F. Barnsley discovered the Fractal Transform ™ which automatically detects fractal codes in real-world images (digitized photographs) Fractal geometry has been applied to such diverse fields as the stock market, chemical industry, meteorology, and computer graphics. In addition, the beauty of fractals has made them a key element in computer graphics. A coastline, if measured down to its least irregularity, would tend toward infinite length just as does the snowflake curve

In this paper, collage grammars are related to self-affinity and self-similarity being fundamental concepts in fractal geometry, a flourishing field of modern mathematics with significant applications to picture processing and computer graphics (see, e.g., [l, 10, 11,20,23,24] complex objects using self-reference.

2. Then we need to generate the L-System which will be the set of instructions for the turtle. We define a function called create_l_system which receives the number of iterations, the axiom and the production rules. It starts with the axiom and uses an auxiliary variable called end_string if iteration is equal to 0 it will return the axiom since some fractals can be plot with iterations equal to 0
3. That is an interesting fractal indeed. But it crosses itself all over the place - starting at teragon 3 and increasingly for each level. It turns out that the turtle can do some clever flipping on alternating segments (the two diagonal ones), to transform this into a plane-filling, self-avoiding, fractal curve

Fractals became important in the study of polymers and even the study of nuclear safety [Gleick 1987]. Geologists used fractal geometry to describe the particular bumpiness of earth's surface and metallurgists found the same for the surfaces of different kinds of steel. Fractals found their way into computer graphics AP ® Computer Science A Major Lab10 The Square Fractal program 80, 100 & 110 Point Versions Assignment Purpose: The purpose of this program is to display a sophisticated knowledge of recursion by writing a program that uses a variety of recursive features. Write a program that draws a square fractal. Fractals are images that keep repeating their own image in ever-smaller versions Step 6: How to control what fractals you generate . You might wish to imagine a fractal in your head, or draw a rough sketch on paper, and then calculate what affine transformations can be used to generate it. This can actually be done fairly easily. The secret is to consider the layout of the self-similar pieces of the fractal Mathematics for computer graphics, Cambridge University Press, Like some fractals, the function exhibits self-similarity: every zoom (red circle) is similar to the global plot. 10 . This can also be done with a square pyramid and five copies instead. 19 . Menger sponge (1926). 3. Fractals in computer graphics. The biggest use of fractals in everyday live is in computer science. Many image compression schemes use fractal algorithms to compress computer graphics files to less than a quarter of their original size. Computer graphic artists use many fractal forms to create textured landscapes and other intricate models For example, we can decompose the unit square into 4 smaller squares, each of side length 1/2; or we can decompose it into 25 squares, each of side length 1/5. Here, the number of self-similar pieces is 4 (or 25) and the scaling factor is 2 (or 5). Thus, the dimension of a square is 2 since log (4) / log(2) = log (25) / log (5) = 2
